Most important for the preservation of health and vitality are sunlight and air. They are just as necessary for growth and perpetuation of life as are liquid and solid food. “When the sun does not enter, thy physician enters,” says an old proverb. It has been found that the greatest mortality occurs in the narrow streets of cities and in houses having northern exposure. The inhabitants of southern mountain slopes are stronger and healthier than those living on the northern sides. Inhabitants of secluded valleys where the sun rises late and sets early are generally afflicted with peculiar diseases, chiefly due to a lack of direct sunlight and its salutary power to dissipate and decompose noxious vapors that accumulate in dark and low places.
